[0002] Solid-liquid separation refers to the operation of separating suspended matter in water. Common separation methods include extrusion separation, filtration separation, centrifugal separation, drying separation, etc., which correspond to the dehydration requirements of different water bodies. At present, for the separation method of extrusion, the existing solid-liquid separation device adopts the method of inputting the mixed liquid into a channel with spiral blades for extrusion, so that the liquid in the mixed liquid is filtered out through the side wall filter, and the solid material is output after squeezing open the elastic plug at the outlet end of the channel to achieve solid-liquid separation.
[0003] The discharge mechanism of the existing solid-liquid separation device is usually an elastic plug that is blocked in the channel by spring force, which limits the distance between the plug and the extrusion channel to ensure that the solid material is gradually extruded without causing the liquid to leak out. However, the above arrangement will limit the discharge end area of the extrusion channel and the discharge is very slow, which will lead to low solid-liquid separation efficiency of the solid-liquid separation device, and thus make the solid-liquid separation device unsuitable for solid-liquid separation of large volumes of mixed liquids and difficult to apply to industrial production that requires ensuring high discharge efficiency.

[0019] Therefore, the utility model provides the following effects and / or advantages:
[0020] 1. The present application first drives the extrusion mechanism and the upper pressure seat down to the lower end of the feed hole for closure through the lifting drive device, and the extrusion member presses the solid material in the extrusion channel down to the feed hole, and at the same time, the liquid in the extrusion channel is filtered out through the filtrate layer and then discharged, to achieve the first-level solid-liquid separation. When the solid content of the material in the feed hole is large, the lifting drive device drives the extrusion mechanism and the upper pressure seat to rise and reset, and the solid material in the feed hole is squeezed and moved into the discharge space, and the suction device sucks the liquid carried by the solid material in the discharge space through a number of suction holes, to achieve the second-level solid-liquid separation, and then the solid material is discharged.

[0021] 2. The present application sets the outer peripheral end of the discharge space in a slope shape so that the solid material can slide down to the outside under the action of its own weight after entering the discharge space, thereby reducing the extrusion discharge pressure at the discharge end of the extrusion channel and further reducing the driving burden of the rotary drive device. At the same time, through the cooperation of the evenly distributed liquid extraction holes and the first negative pressure chamber and the second negative pressure chamber, the liquid carried by the solid material in the discharge space can be evenly sucked out by the suction device, thereby further improving the effect of the secondary solid-liquid separation and improving the purity of the solid material when it is discharged.
[0022] 3.

[0024] 5. This application further reduces the driving burden of the first motor by adding a second motor, and drives the shaft to rotate synchronously through the second motor and the first motor distributed up and down, ensuring the stability of the shaft rotation, avoiding the shaft swing when the spiral blade extrude materials, improving the stability of the extrusion drive device driving the spiral blade to extrude materials, and improving the feasibility of the solid-liquid separation device for large-volume mixed liquid solid-liquid separation in industrial production. At the same time, a number of telescopic cylinders drive the extrusion mechanism, and the upper pressure seat descends to extrude the solid material in the discharge space and then rises and resets, which can also prevent the shaft and the spiral blade from locking, and prevent the discharge space from being blocked.
[0025] 6. The present application adds a sweeping piece to scrape and squeeze the solid material in the discharge space so that it can fully contact the filtrate holes on the opposite sides of the upper pressure seat and the lower pressure seat and then fall after dehydration, thereby improving the dehydration efficiency of the solid material, increasing the extrusion force when discharging the solid material in the discharge space, further improving the discharge speed of the solid material, and preventing the solid material from blocking the discharge space, thereby improving the discharge stability.
[0026] 7. The present application uses the auxiliary drive of the sweeping motor to prevent the sweeping piece from rotating with the rotating shaft so that a number of sweeping rods scrape and squeeze the solid materials in the discharge space. This may cause the sweeping rods to swing or even break due to the resistance of the solid materials, resulting in a decrease in the working performance of the sweeping piece or even loss of function. This improves the structural strength of the sweeping piece, thereby improving the stability of the sweeping piece during operation.

[0037] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:
[0038] refer to Figure 1-9 , a highly adaptable solid-liquid separation device, comprising:
[0039] The extrusion mechanism 2 comprises an extrusion channel 21 arranged vertically and used for inputting a mixed liquid containing liquid and solid materials, a filtrate layer 22 for filtrating the liquid is arranged on the side wall of the extrusion channel 21, and an extrusion member 23 driven by an extrusion driving device 24 to extrude the material is arranged in the extrusion channel 21;
[0040] Specifically, the mixed liquid is input into the extrusion channel 21 through the corresponding feeding mechanism 1, the extrusion mechanism 1 is arranged on the top of the extrusion mechanism 2 and the discharge port is connected to the upper end of the extrusion channel 21;
[0041] The discharge mechanism 3 includes an upper press seat 33 and a lower press seat 34 which are spaced apart from each other and form a discharge space 31 therebetween. The upper press seat 33 is connected to the extrusion mechanism 2. A feed hole 334 which connects the extrusion channel 21 and the discharge space 31 is provided through the middle of the upper press seat 33. A plurality of liquid extraction holes 32 which connect the discharge space 31 and the corresponding suction device are provided on opposite sides of the upper press seat 33 and the lower press seat 34. Specifically, the suction device can extract liquid and then discharge it.
[0042] A lifting drive device 6, used for driving the feeding mechanism 1, the extruding mechanism 2 and the upper pressing seat 33 to move up and down;
[0043] The lifting drive device 6 first drives the feeding mechanism 1, the extruding mechanism 2 and the upper pressure seat 33 to descend to the lower end of the feeding hole 334 to be closed. After the feeding mechanism 1 inputs the mixed liquid into the extrusion channel 21, the extrusion member 23 squeezes the solid material in the extrusion channel 21 and presses it down into the feeding hole 334, and at the same time squeezes the liquid in the extrusion channel 21 to be filtered out through the filtrate layer 22 and then discharged, so as to achieve the first-level solid-liquid separation and make the solid content of the material in the feeding hole 334 large, the lifting drive device 6 then drives the feeding mechanism 1, the extruding mechanism 2 and the upper pressure seat 33 to rise and reset, and the solid material in the feeding hole 334 is squeezed and moved into the discharge space 31, and the suction device sucks the liquid carried by the solid material in the discharge space 31 through the plurality of the suction holes 32, so as to achieve the second-level solid-liquid separation and then the solid material is discharged.
[0044] The arrangement of the above-mentioned structure, through the addition of the discharging mechanism 3, makes the discharging space 31 extend the travel of the solid material after being squeezed out of the extrusion channel 21, and further realizes solid-liquid separation of the solid material carrying the liquid through the suction device in the discharging space 31, further improving the purity of the solid material when discharging, so that the extrusion channel 21 is vertically arranged to utilize the dead weight of the solid material to accelerate the extrusion rate and reduce the burden of the extrusion drive device 24. The extrusion mode can be realized, and the solid-liquid separation efficiency is improved and the energy consumption is reduced while ensuring the solid-liquid separation effect, and the service life of the extrusion drive device 24 is extended. At the same time, the peripheral port of the discharging space 31 can be set as a solid material output port, which greatly increases the discharging area and the discharging efficiency, thereby ensuring the discharging efficiency of the solid-liquid separation device when it is applied to industrial production, making it suitable for solid-liquid separation of large volumes of mixed liquids, and improving the adaptability of the solid-liquid separation device.
[0045] In order to improve the effect of the secondary solid-liquid separation in the discharge space 31, the outer peripheral end of the discharge space 31 is inclined outward and extends downward in a slope shape, and the upper pressure seat 33 and the lower pressure seat 34 respectively form a first negative pressure chamber 331 and a second negative pressure chamber 341 connected to the suction device, and a plurality of the liquid extraction holes 32 respectively connect the first negative pressure chamber 331 and the second negative pressure chamber 341 with the discharge space 31. Therefore, by setting the outer peripheral end of the discharge space 31 in a slope shape, the solid material can slide outward under the action of its own weight after entering the discharge space 31, reducing the extrusion discharge pressure at the discharge end of the extrusion channel 21, further reducing the driving burden of the rotary drive device, and at the same time, through the cooperation of the evenly distributed liquid extraction holes 32 and the first negative pressure chamber 331 and the second negative pressure chamber 341, the liquid carried by the solid material in the discharge space 31 can be evenly sucked by the suction device, further improving the effect of the secondary solid-liquid separation and improving the purity of the solid material when it is discharged.
[0046] In order to improve the structural strength of the discharging mechanism 3, a plurality of first reinforcing plates 332 and a plurality of second reinforcing plates 342 are fixedly arranged in the first negative pressure chamber 331 and the second negative pressure chamber 341 at intervals in the circumferential direction, respectively. A plurality of first reinforcing plates 332 are provided with gaps between the upper ends of the plurality of first reinforcing plates 332 and the inner top of the first negative pressure chamber 331, and a plurality of second reinforcing plates 342 are provided with gaps between the upper ends of the plurality of second reinforcing plates 342 and the inner top of the second negative pressure chamber 341. The plurality of first reinforcing plates 332 and the plurality of second reinforcing plates 342 respectively separate the first negative pressure chamber 331 and the second negative pressure chamber 341 into a plurality of first negative pressure areas 333 and a plurality of second negative pressure areas 343 that are connected. Thus, the structural strength of the upper press seat 33 and the lower press seat 34 is improved by adding a plurality of first reinforcing plates 332 and a plurality of second reinforcing plates 342. At the same time, the airflow between the plurality of first negative pressure areas 333 and the plurality of second negative pressure areas 343 can be reduced, the negative pressure suction strength of the plurality of first negative pressure areas 333 and the plurality of second negative pressure areas 343 can be improved, and the negative pressure liquid extraction effect can be improved.
[0047] In order to further improve the effect of secondary solid-liquid separation in the discharge space 31, it also includes a frame 4, and the feeding mechanism 1, the extruding mechanism 2, and the discharge mechanism 3 are linked and connected in sequence from top to bottom and are arranged in the frame 4, the upper pressure seat 33 is connected to the frame 4 for sliding up and down, and the lower pressure seat 34 is fixedly connected to the frame 4, and the lifting drive device 6 includes a plurality of telescopic cylinders whose telescopic ends are connected to the feeding mechanism 1; when the suction device sucks the liquid carried by the solid material in the discharge space 31 through the plurality of liquid suction holes 32, the plurality of telescopic cylinders drive the feeding mechanism 1, the extruding mechanism 2, and the upper pressure seat 33 to descend and squeeze the solid material in the discharge space 31 and then rise and reset, thereby improving the suction strength of the first negative pressure chamber 331 and the second negative pressure chamber 341 on the liquid carried by the solid material in the discharge space 31 through the filtrate hole 221, thereby realizing extrusion dehydration.
[0048] In order to improve the driving stability of the extrusion drive device 24, the extrusion drive device 24 includes a rotating shaft 241 that vertically penetrates the feeding mechanism 1, the extrusion channel 21, the feeding hole 334, the discharging space 31 and the lower pressure seat 34, a first motor 242 is arranged at the bottom of the lower pressure seat 34 and the rotating output end is connected to the lower end of the rotating shaft 241, and a second motor 243 is arranged at the top of the frame 4 and the rotating output end is connected to the upper end of the rotating shaft 241. The extrusion member 23 is configured as a spiral blade fixedly mounted on the rotating shaft 241. Therefore, when the solid-liquid separation device is used in the solid-liquid separation of a large volume of mixed liquid, the driving burden of the first motor 242 is further reduced by adding the second motor 243, and the second motor 243 and the first motor 242 distributed up and down synchronously drive the rotating shaft 241 to rotate, thereby ensuring the stability of the rotation of the rotating shaft 241, avoiding the deviation of the rotating shaft 241 when the spiral blades extrude materials, improving the stability of the extrusion drive device 24 driving the spiral blades to extrude materials, and improving the feasibility of applying the solid-liquid separation device to the solid-liquid separation of large volumes of mixed liquids in industrial production.
[0049] At the same time, when the suction device sucks the liquid carried by the solid material in the discharge space 31 through the plurality of liquid suction holes 32, the plurality of telescopic cylinders drive the feeding mechanism 1, the extruding mechanism 2, and the upper pressure seat 33 to descend and squeeze the solid material in the discharge space 31 and then rise and reset, which can also prevent the rotating shaft 241 and the spiral blade from locking, and prevent the discharge space 31 from being blocked.
[0050] In order to further improve the driving stability of the extrusion drive device 24, the bottom of the lower pressing seat 34 is concave to form a mounting groove 344, and the rotating output end of the first motor 242 is arranged in the mounting groove 344. The side of the lower pressing seat 34 is fixed with a plurality of discharge grooves 35, one end of which corresponds to the outer port of the discharge space 31 and the other end is inclined outward and extends downward. Therefore, the position of the rotating output end of the first motor 242 is moved up by the setting of the mounting groove 344, so that the length of the rotating shaft 241 can be shortened accordingly, and the distance between the rotating output end of the first motor 242 and the extrusion channel 21 is shortened, thereby improving the stability of the first motor 242 driving the rotating shaft 241 to rotate, and at the same time, the setting of the discharge groove 35 realizes the stable guidance of the discharge of solid materials.
[0051] In order to further improve the discharge efficiency of the discharge space 31, it also includes a sweeping mechanism 5, which includes a sweeping piece 51 arranged in the discharge space 31 and the middle part of which is fixedly sleeved on the rotating shaft 241. The middle part of the sweeping piece 51 is sealed and screwed with the top of the lower press seat 34, so as to prevent solid materials from entering between the sweeping piece 51 and the rotating shaft 241 and the lower press seat 34, forming a blockage and affecting the operation of the mechanism. The outer peripheral end of the sweeping piece 51 is inclined outward and extends downward to the outside of the discharge space 31 to form a plurality of circumferentially spaced sweeping rod portions 511; when the first motor 242 and the second motor 243 drive the rotating shaft 241 to rotate, the sweeping piece 51 is driven to rotate, and the plurality of sweeping rod portions 511 are driven to rotate. The part 511 scrapes and squeezes the solid material in the discharge space 31, so that by adding the sweeping piece 51, the solid material in the discharge space 31 is scraped and squeezed so that it can fully contact the filtrate hole 221 on the opposite side of the upper pressure seat 33 and the lower pressure seat 34 to be dehydrated and then fall, thereby improving the dehydration efficiency of the solid material, increasing the extrusion force when the solid material in the discharge space 31 is discharged, further improving the discharge speed of the solid material, and preventing the solid material from clogging the discharge space 31, thereby improving the discharge stability; when the lifting drive device 6 drives the feeding mechanism 1, the extruding mechanism 2 and the upper pressure seat 33 to descend until the lower end of the feed hole 334 is closed, the lower end of the feed hole 334 is against the top middle part of the sweeping piece 51.
[0052] In order to improve the working stability of the sweeping member 51, the sweeping mechanism 5 also includes a ring gear 512 which is arranged on the outside of the discharge space 31 and fixedly connected to the outer ends of the plurality of sweeping rod portions 511, and a sweeping motor 52 which is arranged on the frame 4 and whose rotating output end engages with the ring gear 512 through a driving gear; the sweeping motor 52 auxiliary drives the sweeping member 51 to rotate through the cooperation between the driving gear and the ring gear 512, so that through the auxiliary drive of the sweeping motor 52, when the sweeping member 51 rotates with the rotating shaft 241 to make the plurality of sweeping rod portions 511 scrape and squeeze the solid material in the discharge space 31, it is avoided that the plurality of sweeping rod portions are deflected or even broken due to the resistance of the solid material, resulting in a decrease in the working performance of the sweeping member 51 or even a loss of function, thereby improving the structural strength of the sweeping member 51 and further improving the stability of the sweeping member 51 during operation.
[0053] In order to improve the discharge efficiency of the liquid in the extrusion mechanism 2, the filtrate layer 22 is set as a filter cartridge, and a plurality of filtrate holes 221 are evenly arranged on the side wall of the filter cartridge in the circumferential direction. The extrusion mechanism 2 also includes a sleeve 25 which is sealed and sleeved on the outside of the filter cartridge to form a filtrate cavity 26 between the filter cartridge and a plurality of drainage pipes 27 which are connected to the lower part of the sleeve 25. The lower end of the sleeve 25 is detachably connected to the upper end of the upper pressing seat 33. Therefore, when the extrusion drive device 24 presses down the solid material in the material extrusion channel 21, part of the liquid in the extrusion channel 21 is simultaneously extruded through the plurality of filtrate holes 221 to the filtrate cavity 26 and then discharged through the plurality of drainage pipes 27, thereby improving the discharge efficiency of the liquid in the extrusion mechanism 2.
[0054] In order to improve the efficiency of primary solid-liquid separation, the feeding mechanism 1 is configured as a hopper with a gradually decreasing inner diameter in the lower half to form a sedimentation zone 14, and the feeding mechanism 1 includes a feeding port 11 and a discharging port 12 distributed up and down, and an overflow port 13 located between the feeding port 11 and the discharging port 12, an annular overflow groove 15 with an opening facing upward is fixed on the outer wall of the upper end of the sedimentation zone 14, a plurality of overflow pipes 16 are penetrated through the bottom of the overflow groove 15, and the upper port of the hopper forms the overflow port 13, the solid material and part of the liquid in the feeding mechanism 1 sink into the extrusion channel 21, and the remaining liquid is discharged through the overflow port 13, the overflow groove 15 and the overflow pipe 16 in sequence. Thus, by configuring the overflow port 13, the overflow trough 15 and the overflow pipe 16, a primary separation step is added before the primary separation and the secondary separation, thereby increasing the solid content of the mixed liquid entering the extrusion channel 21, and improving the efficiency of the primary solid-liquid separation, thereby improving the overall solid-liquid separation effect and efficiency, and further improving the adaptability of the solid-liquid separation device to large-volume mixed liquids in industrial production.
[0055] Working principle:
[0056] The lifting drive device 6 first drives the feeding mechanism 1, the extruding mechanism 2 and the upper pressing seat 33 to descend until the lower end of the feeding hole 334 is closed, and the feeding mechanism 1 inputs the mixed liquid into the extruding channel 21;
[0057] The extrusion member 23 squeezes the solid material in the extrusion channel 21 into the feed hole 334, and squeezes the liquid in the extrusion channel 21 to be filtered out through the filtrate layer 22, thereby achieving a primary solid-liquid separation so that the solid content of the material in the feed hole 334 is relatively large.
[0058] After the extrusion member 23 has been extruded for a certain period of time, the lifting drive device 6 drives the feeding mechanism 1, the extruding mechanism 2 and the upper pressure seat 33 to rise and reset, and the solid material in the feeding hole 334 is squeezed and moved into the discharge space 31. The suction device sucks the liquid carried by the solid material in the discharge space 31 through the plurality of liquid suction holes 32. After the secondary solid-liquid separation is achieved, the solid material is discharged.
